"Nie mam pasty do zębów."

Translation: I do not have toothpaste.

[Mr.aljabry]

For some reason it, I need say "I don't have any toothpaste", instead of simply saying "I don't have toothpaste"

[Ash473779]

Is zębów here a plural? And what grammatical case is it in?

[Jellei]

Plural, Genitive.

[gbaldacci1309]

I do not think the "pasty", in this case, is plural. I believe it is "pasty" because the negated accusative verb (mice) takes on genitive and genitive for "pasta" is "pasty". Is this correct?

[Jellei]

Yes, you're right. But that comment was about "zębów" :)

I'm confused by 'mice', I guess it's a typo plus lack of Polish signs of "mieć"?

[Kelvin.HSO]

Pasta do zębów looks like "pasta de dente" in Portuguese

[HectorPinh5]

Sim

[Y4M91]

how's the declension for pasty do zębów like?

[Jellei]

https://en.wiktionary.org/wiki/pasta#Noun_23 - that's the declension for "pasta", and then "do zębów" will always stay unchanged, as it's a prepositional phrase.

[jamielniak]

Eu não tenho pasta de dentes
